DOCS

When the :docs command is given a stringp argument it searches the
text produced by :doc and :more-doc and lists all the
documented topics whose text contains the given string. For purposes of this
string matching we ignore distinctions of case and the amount and kind (but
not presence) of white space. We also treat hyphen as whitespace.

However, the following examples show how :docs can be used on other than
string patterns.

The data base of formatted documentation strings is structured into
sections. Within a section are topics. Each topic has a one-liner,
some notes, and some detailed discussions. The :docs command
provides a view of the entire data base.

:docs takes one argument, as described below:

arg effect

* list all section headings in the data base
** list all section headings and all topics within
each section
name list all topics in the section named name (where
name is some symbol other than * and **). This
is always the same as :doc name.
pattern list all topics whose :doc or :more-doc text
mentions the string pattern. For purposes of this
string matching we ignore distinctions of case and
the amount and kind (but not presence) of white
space. We also treat hyphen as whitespace.
